The dual-pivot brake further includes an exoskeleton bridge including a two-piece bridge member consisting of first and second bridge members. The first and second bridge members are interconnected together by first and second axles, respectively. The first and second caliper arms are pivotally mounted on the first and second axles respectively and selectively move toward or away from each other in the operation of the dual-pivot brake.

Abstract: A brake system for bicycles includes two pivotably connected first and second arms and two brake pads are respectively connected to the first and second arms. A cable unit is connected to the second arm and includes a brake cable. A link unit includes a first link which is connected between the second arm and the brake cable. A second link has a first end connected to the first arm and a second end of the second link is pivotably connected to a mediate portion of the first link. The distance between the two ends of the first link is longer than the distance between the second end of the first link to the second end of the second link. The brake cable is lifted with less force, the first link lifts the second link which moves the first arm to pivot to stop the wheel rim.

Abstract: A bicycle brake actuated by a control cable has a first main brake arm and a second main brake arm mounted for pivotable movement with respect to the first main brake arm. A first transfer brake arm is pivotally connected to the first main brake arm, and a second transfer brake arm is pivotally connected to the first transfer brake arm and pivotally connected to the second main brake arm. The first main brake arm has a cable guide for receiving the control cable. The first transfer brake arm has a cable anchor for receiving the control cable, the control cable extending between the cable guide and the cable anchor. The first main brake arm and second main brake arm each support a brake shoe and apply braking force to a wheel when actuated.

Abstract: In the specification and drawing a new brake system and a two-wheeled vehicle using the same are described. The new brake system includes a first brake to apply a first brake force on a first wheel of a vehicle and transfers the first brake force to physically actuate a second brake to brake a second wheel of the vehicle. A new-designed cantilever brake is disclosed to transfer the first brake force to actuate the second brake.

Abstract: There is provided a caliper brake attachment tool which comprises: a supporting rod; a fixed part provided to one end side of the supporting rod capable of fixing an existing caliper brake; an applying part provided to the other end side of the supporting rod and applicable to a seat tube of the bicycle; and an engaging recess provided between the fixed part and the applying part in the supporting rod engageable with a bridge to connect a right-and-left pair of seat stays of the bicycle.

Abstract: The bicycle wheel of the present invention is made of composite material and has two opposite braking surfaces, each of which is coated with a fluoride polymer layer. Specifically, the braking surfaces are sand blasted to remove a releasing agent layer coated on the wheel. The wheel is, thereafter, placed in a spraying machine at about 100 degree Celsius and then the braking surfaces are spray-coated with a material selected from the group consisting of polytetrafluoro ethylene, fluoride ethylene-propylene copolymer, polyfluoroalkyl, ethylene-tetrafluoro ethylene copolymer and the mixture thereof until a thickness of the material is bigger than 0.4 cm. Thereafter, the wheel is gradually heated to make the material set and form the fluoride polymer layers.

Abstract: A quick-release device of a bicycle brake cable includes a brake arm mounted on a frame of the bicycle, a guider selectively slidably mounted on a free end of the brake arm and a safe lever pivotally mounted in the brake arm. The brake arm includes a groove defined along an axis thereof. The guider is hollow to allow the brake cable extending therethrough. The safe lever includes a pivot point that divides the safe lever into a press portion and a stop portion extending toward the guider to prevent the guider from an accidental operation due to an improper force.

Abstract: Described herein is a bicycle brake assembly which comprises a torsion spring attached to brake arms by bosses. The torsion spring simultaneously attaches to a slide bolt, while the slide bolt attaches to a slide member. When the rider applies pressure upon the bike handlebar levers, the tension from the bicycle cable pulls the slide bolt and engaged slide member upward. The torsion spring attached to the slide bolt flexes, thereby pulling the upper brake arms toward each other. The lower brake arm movement towards the bicycle rim results in abutment of brake shoes against the bicycle rim.

Abstract: A brake includes two rockers, two shoes attached to the rockers and two linings attached to the shoes. The brake pinches a rim without overheating the rim. The rim includes two walls and a bridge. Each of the walls includes a first portion within the bridge, a second portion beside the bridge so that the bridge performs as a heat sink and supports the second portion and a third portion beyond the bridge in order to clamp a tire. The two linings pinch the second portions of the walls. An anchor attaches the top of each of the shoes to the related rocker and is vertically spaced from the linings.

Abstract: A fiber reinforced plastic bicycle wheel rim having an aerodynamic section is formed of two mating halves, without additional structural reinforcing members, using laminations of layers of unidirectional fibers crossing one another and having semicircular layers of non-crossing fibers orientated parallel to a point of tangency, the non-crossing layers being proximate tire well apexes and the spoke bed, including, in a preferred embodiment, a lamination of machinable materials at the braking surfaces.
